ABSTRACT

Substituted imidazolylmethyloxiranes and substituted imidazolylpropenes of the general formula I ##STR1## where R 1  and R 2  are alkyl, cycloalkyl, cycloalkenyl, tetrahydropyranyl, norbornyl, pyridyl, naphthyl, biphenyl or phenyl, 
     D is oxygen or a single bond, 
     E is H, F, Cl or Br, 
     X, Y and Z are hydrogen, halogen, nitro, cyano, alkyl, haloalkyl, alkoxy, unsubstituted or substituted amino, unsubstituted or substituted mercapto, acyl, alkoxycarbonyl, hydroxyalkyl or substituted or unsubstituted phenyl, and acid addition salts and metal complexes thereof tolerated by plants, 
     processes for their manufacture, and fungicides containing them.

The present invention relates to novel substituted imidazolylmethyloxiranes and substituted imidazolylpropenes, processes for their preparation and fungicides containing them, and methods for controlling fungi.

It is known that imidazolyloxiranes, for example cis-2-(imidazol-1-ylmethyl)-2-(4-fluorophenyl)-3-(2,6-difluorophenyl)-oxirane (DE-32 18 130) can be used as fungicides. However, the fungicidal actions are unsatisfactory.

We have found that substituted imidazolylmethyloxiranes and substituted imidazolylpropenes of the formula I ##STR2## where R¹ and R² are identical or different and are each C₁ -C₈ -alkyl, C₃ -C₈ -cycloalkyl, C₅ -C₈ -cycloalkenyl, tetrahydropyranyl, norbornyl, pyridyl, naphthyl, biphenyl or phenyl, and these radicals may be monosubstituted to tri-substituted by halogen, nitro, phenoxy, amino, alkyl, alkoxy or haloalkyl, each of 1 to 4 carbon atoms, and D is O or a single bond, E is H, F, Cl or Br and X, Y and Z are identical or different and are each hydrogen, halogen, nitro, cyano, C₁ -C₃ -alkyl, C₁ -C₃ -haloalkyl, C₁ -C₃ alkoxy, amino which is unsubstituted or substituted by C₁ -C₃ -alkyl or C₁ -C₃ -acyl, unsubstituted or C₁ -C₃ -alkyl-substituted mercapto, C₁ -C₃ -acyl, C₁ -C₃ -alkoxycarbonyl, C₁ -C₃ -hydroxyalkyl or unsubstituted or substituted phenyl, and X, Y and Z cannot simultaneously be hydrogen, and their plant-tolerated acid addition salts and metal complexes have a better fungicidal action than known azole compounds.

The compounds of the formula I contain asymmetric carbon atoms and can therefore occur as enantiomers and diastereomers. In the case of the novel compounds, the mixtures of diastereomers can be separated in a conventional manner, for example on the basis of their different solubilities or by column chromatography, and can be isolated in pure form. The racemates of the novel compounds can be resolved by known methods, for example by salt formation with an optically active acid, separation of the diastereomeric salts and liberation of the enantiomers by means of a base. Both the pure diastereomers or enantiomers and the mixtures of these obtained in the synthesis can be used as fungicides.

R¹ and R² are each, for example, C₁ -C₈ -alkyl, in particular C₁ -C₄ -alkyl, such as methyl, ethyl, isopropyl, n-propyl, n-butyl, sec-butyl, tert-butyl, n-pentyl or neopentyl, 1-naphthyl, 2-naphthyl, p-biphenyl, phenyl, halophenyl, such as 2-chlorophenyl, 2-fluorophenyl, 2-bromophenyl, 3-chlorophenyl, 3-bromophenyl, 3-fluorophenyl, 4-fluorophenyl, 4-chlorophenyl, 4-bromophenyl, 2,4-dichlorophenyl,2,3-dichlorophenyl,2,5-dichlorophenyl, 2,6-dichlorophenyl, 2-chloro-6-fluorophenyl or 2-chloro-4-fluorophenyl, C₁ -C₄ -alkoxyphenyl, such as 2-methoxyphenyl, 3-methoxyphenyl, 4-methoxyphenyl, 2,4-dimethoxyphenyl or 3,4-dimethoxyphenyl, C₁ -C₄ -alkylphenyl, such as 4-ethylphenyl, 4-isopropylphenyl, 4-tert-butylphenyl or 4-tert-butoxyphenyl, 2-chloro-6-methylphenyl, 3-phenoxyphenyl, 4-phenoxyphenyl, 3-nitrophenyl, 4-nitrophenyl, 3-aminophenyl, 4-aminophenyl, 2-aminophenyl, 2-trifluoromethylphenyl, 3-trifluoromethylphenyl, 4-trifluoromethylphenyl, 3-pyridyl, tetrahydropyranyl, cyclopropyl, cyclopentyl, cyclohexyl, 2-cyclohexenyl, 3-cyclohexenyl or norbornyl.

X, Y and Z are each, for example, hydrogen, methyl, ethyl, propyl, isopropyl, trifluoromethyl, methoxy, ethoxy, methylamino, dimethylamino, acetylamino, diacetylamino, methylthio, acetyl, methoxyacetyl, phenyl, halophenyl, chlorophenyl or hydroxyethyl, and X, Y and Z cannot simultaneously be hydrogen, i.e. one or more of the radicals X, Y and Z differ from hydrogen.

Acid addition salts are, for example, the hydrochlorides, bromides, sulfates, nitrates, phosphates, oxalates and dodecylbenzenesulfonates. The activity of the salts is attributable to the cation, so that the anion is generally unimportant. The novel active ingredient salts are prepared by reacting an imidazolylmethyl oxirane (I) with an acid.

Metal complexes of the active ingredients I or their salts can be formed, for example, with copper, zinc, tin, manganese, iron, cobalt or nickel, by reacting the imidazolylmethyloxirane with a corresponding metal salt, for example with copper sulfate, zinc chloride, tin chloride or manganese sulfate.

The compounds of the formula I in which D is O and E is H can be prepared, for example, by

a) reacting a compound of the formula II ##STR3## where R¹ and R² have the abovementioned meanings and L is a leaving group which can be substituted by a nucleophile (e.g. halogen or OH), with a compound of the formula III ##STR4## where Me is hydrogen, a metal atom (e.g. Na or K) or trimethylsilyl and X, Y and Z have the abovementioned meanings, or

b) converting a compound of the formula IV ##STR5## where R¹, R², X, Y and Z have the abovementioned meanings, into the epoxide.

If Me is hydrogen, reaction a) is carried out, for example, in the presence or absence of a base and in the presence or absence of a solvent or diluent, with or without the addition of a reaction accelerator, at from 10° to 120° C. The preferred solvents and diluents include ketones, such as acetone, methyl ethyl ketone and cyclohexanone, nitriles, such as acetonitrile and propionitrile, alcohols, such as methanol, ethanol, isopropanol, n-butanol and glycol, esters, such as ethyl acetate, methyl acetate and butyl acetate, ethers, such as tetrahydrofuran, diethyl ether, dimethoxyethane, dioxane and diisopropyl ether, amides, such as dimethylformamide, dimethylacetamide and N-methylpyrrolidone, and dimethyl sulfoxide, sulfolane and mixtures of these.

Suitable bases, which may also be used as acid acceptors in the reaction are, for example, alkali metal hydroxides, such as lithium hydroxide, sodium hydroxide or potassium hydroxide, alkali metal carbonates, such as sodium carbonate, potassium carbonate or cesium carbonate, or sodium bicarbonate, potassium bicarbonate, cesium bicarbonate, pyridine or 4-dimethylaminopyridine. However, other conventional bases may also be used.

Preferred reaction accelerators are metal halides, such as sodium iodide or potassium iodide, quaternary ammonium salts, such as tetrabutylammonium chloride, bromide, iodide or bisulfate, benzyltriethylammoniumchloride or bromide, and crown ethers, such as 12-crown-4, 15-crown-5, 18-crown-6, dibenzo-18-crown-6 or dicyclohexano-18-crown-6.

The reaction is generally carried out at, for example, from 20° to 150° C., under atmospheric or super atmospheric pressure, continuously or batchwise.

If Me is a metal atom, reaction a) is carried out, for example, in the presence or absence of a solvent or diluent and with or without the addition of a strong inorganic or organic base, at from -10° to 120° C. The preferred solvents and diluents include amides, such as dimethylformamide, diethylformamide, dimethylacetamide, diethylacetamide, N-methylpyrrolidone, hexamethylphosphorotriamide, sulfoxides, such as dimethyl sulfoxide, and finally sulfolane.

Suitable bases, which may also be used as acid acceptors in the reaction, are, for example, alkali metal hydrides, such as lithium hydride, sodium hydride and potassium hydride, alkali metal amides, such as sodium amide and potassium amide, as well as sodium tert-butoxide, potassium tert-butoxide, triphenylmethyllithium, triphenylmethylsodium, triphenylmethylpotassium, naphthalenelithium, naphthalenesodium and naphthalenepotassium.

Examples of suitable diluents for reaction b) are polar organic solvents, such as nitriles, e.g. acetonitrile, sulfoxides, e.g. dimethyl sulfoxide, formamides, e.g. dimethylformamide, ketones, e.g. acetone, ethers, e.g. diethyl ether or tetrahydrofuran, and in particular chlorohydrocarbons, e.g. methylene chloride and chloroform.

The reaction is carried out in general at, for example, from 0° to 100° C., preferably from 20° to 80° C. In the presence of a solvent, it is advantageously carried out at the boiling point of the particular solvent.

The novel starting compounds II are obtained, for example, by epoxidation of the corresponding olefins V ##STR6## (cf. G. Dittus in Houben-Weyl-Muller, Methoden der Organischen Chemie, Georg Thieme Verlag, Stuttgart, 1965, Vol. VI, 3, page 385 et seq.).

The compound V is prepared by halogenating or oxidizing olefins of the formula IX ##STR7## by known methods in the allyl position.

Suitable halogenating reagents are N-chloro- and N-bromosuccinimide in halohydrocarbons, such as carbon tetrachloride, trichloroethane or methylene chloride, temperatures of from 20° to 100° C. being employed. For the allyl oxidation, peresters, such as tert-butyl perbenzoate or tert-butyl peracetate, are used in the presence of a heavy metal salt, eg. copper(I) chloride or copper(I) bromide. The reaction is carried out in an inert solvent at from 10° to 100° C.

The allyl halides or alcohols V thus obtained are then converted into the corresponding epoxides II (L=halogen or OH). For this purpose, the olefins V are oxidized with a peroxycarboxylic acid, such as perbenzoic acid, 3-chloroperbenzoic acid, 4-nitroperbenzoic acid, monoperphthalic acid, peracetic acid, perpropionic acid, permaleic acid, monopersuccinic acid, perpelargonic acid or trifluoroperacetic acid, in an inert solvent, preferably a chlorohydrocarbon, eg. methylene chloride, chloroform, carbon tetrachloride or dichloroethane, or, if required, in acetic acid, ethyl acetate, acetone or dimethylformamide, in the presence or absence of a buffer, such as sodium acetate, sodium carbonate, disodium hydrogen phosphate or Triton B. The reaction is carried out at from 10° to 100° C. and, if required, is catalyzed with, for example, iodine, sodium tungstate or light. Alkaline solutions of hydrogen peroxide (about 30% strength) in methanol, ethanol, acetone or acetonitrile, at from 25° to 30° C., and alkyl hydroperoxides, e.g. tert-butyl hydroperoxide, with the addition of a catalyst, e.g. sodium tungstate, pertungstic acid, molybdenum hexacarbonyl or vanadyl acetylacetonate, are also suitable for the oxidation. Some of the stated oxidizing agents can be produced in situ.

While the resulting epoxyhalides II (L=halogen) can be reacted immediately by process a), the corresponding epoxyalcohols II (L=OH) are converted into, for example, reactive esters, which are then reacted with the compounds III by process a).

The reactive esters which can be reacted with III are prepared by generally known methods (Houben-Weyl-Muller, Methoden der organischen Chemie, Georg Thieme Verlag, Stuttgart, 1955, Volume 9, pages 388, 663 and 671). Examples of such esters are methanesulfonates, trifluoromethanesulfonates, 2,2,2-trifluoroethanesulfonates, nonafluorobutanesulfonates, 4-methylbenzenesulfonates, 4-bromobenzenesulfonates, 4-nitrobenzenesulfonates and benzenesulfonates.

The compounds V can be prepared by generally known processes of olefin synthesis (Houben-Weyl-Muller, Methoden der organischen Chemie, Georg Thieme Verlag, Stuttgart, 1972, Vol. V, 1b).

The compounds of the formula IV ##STR8## are obtained, for example, by a) reacting a compound of the formula V ##STR9## where R¹ and R² have the abovementioned meanings and L is a leaving group which can be substituted by a nucleophile, with a compound of the formula III ##STR10## where Me is hydrogen, a metal atom or trimethylsilyl and X, Y and Z have the abovementioned meanings, or

b) reacting a compound of the formula VI ##STR11## where R¹, X, Y and Z have the abovementioned meanings, with a compound of the formula VII ##STR12## where R² has the same meanings as in formula I and R³, R⁴ and R⁵ may be identical or different and are each phenyl, p-carboxyphenyl, p-dimethylaminophenyl, dimethylamino, piperidino, morpholino, alkyl of 1 to 3 carbon atoms or cyclohexyl.

The compounds of the formula I in which E is F, Cl or Br can be prepared, for example, by reacting a compound of the formula VIII ##STR13## where R¹, R² and D have the stated meanings, with a compound of the formula III ##STR14## where X, Y, Z and Me have the abovementioned meanings, in the presence of a thionyl halide.

The reaction is carried out, for example, in the presence or absence of a solvent or diluent at from -30° to 80° C. The preferred solvents and diluents include nitriles, such as acetonitrile or, propionitrile, ethers, such as tetrahydrofuran, diethyl ether, dimethoxyethane, dioxane or diisopropyl ether, and in particular hydrocarbons and chlorohydrocarbons, such as pentane, hexane, toluene, methylene chloride, chloroform, carbon tetrachloride or dichloroethane, or mixtures of these.

The novel starting compounds VIII in which D is O are obtained, for example, by epoxidation of the corresponding olefins X ##STR15## (cf. G. Dittus in Houben-Weyl-Muller, Methoden der Organischen Chemie, Georg Thieme Verlag, Stuttgart, 1965, Vol. VI, 3, page 38 et seq.).

The compounds X can be prepared by generally known methods of aldehyde synthesis (Houben-Weyl-Muller, Methoden der Organischen Chemie, Georg Thieme Verlag, Stuttgart, 1983, Vol. E3).

Generally speaking, the novel compounds are extremely effective on a broad spectrum of phytopathogenic fungi, in particular those from the Ascomycetes and Basidiomycetes classes. Some of them have a systemic action and can be used as foliar and soil fungicides.

The fungicidal compounds are of particular interest for controlling a large number of fungi in various crops or their seeds, especially wheat, rye, barley, oats, rice, Indian corn, lawns, cotton, soybeans, coffee, sugar cane, fruit and ornamentals in horticulture and viticulture, and in vegetables such as cucumbers, beans and cucurbits.

The novel compounds are particularly useful for controlling the following plant diseases:

Erysiphe graminis in cereals,

Erysiphe cichoracearum and Sphaerotheca fuliginea in cucurbits,

Podosphaera leucotricha in apples,

Uncinula necator in vines,

Puccinia species in cereals,

Rhizoctonia species in cotton and lawns,

Ustilago species in cereals and sugar cane,

Venturia inaequalis (scab) in apples,

Helminthosporium species in cereals,

Septoria nodorum in wheat,

Botrytis cinerea (gray mold) in strawberries and grapes,

Cercospora arachidicola in groundnuts,

Pseudocercosporella herpotrichoides in wheat and barley,

Pyricularia oryzae in rice,

Phytophthora infestans in potatoes and tomatoes,

Fusarium and Verticillium species in various plants,

Plasmopara viticola in grapes,

Alternaria species in fruit and vegetables.

The compounds are applied by spraying or dusting the plants with the active ingredients, or treating the seeds of the plants with the active ingredients. They may be applied before or after infection of the plants or seeds by the fungi.

The novel substances can be converted into conventional formulations such as solutions, emulsions, suspensions, dusts, powders, pastes and granules. The application forms depend entirely on the purposes for which they are intended; they should at all events ensure a fine and uniform distribution of the active ingredient. The formulations are produced in known manner, for example by extending the active ingredient with solvents and/or carriers, with or without the use of emulsifiers and dispersants; if water is used as solvent, it is also possible to employ other organic solvents as auxiliary solvents. Suitable auxiliaries for this purpose are solvents such as aromatics (e.g., xylene), chlorinated aromatics (e.g., chlorobenzenes), paraffins (e.g., crude oil fractions), alcohols (e.g., methanol, butanol), ketones (e.g., cyclohexanone), amines (e.g., ethanolamine, dimethylformamide), and water; carriers such as ground natural minerals (e.g., kaolins, aluminas, talc and chalk) and ground synthetic minerals (e.g., highly disperse silica and silicates); emulsifiers such as nonionic and anionic emulsifiers (e.g., polyoxyethylene fatty alcohol ethers, alkyl sulfonates and aryl sulfonates); and dispersants such as lignin, sulfite waste liquors and methylcellulose.

The fungicidal agents generally contain from 0.1 to 95, and preferably from 0.5 to 90, wt % of active ingredient. The application rates are from 0.02 to 3 kg or more of active ingredient per hectare, depending on the type of effect desired. The novel compounds may also be used for protecting materials, for example against Paecilomyces variotii.

The agents and the ready-to-use formulations prepared from them, such as solutions, emulsions, suspensions, powders, dusts, pastes and granules, are applied in conventional manner, for example by spraying, atomizing, dusting, scattering, dressing or watering.

Examples of formulations are given below.

I. 90 parts by weight of compound no. 113 is mixed with 10 parts by weight of N-methyl-α-pyrrolidone. A mixture is obtained which is suitable for application in the form of very fine drops.

II. 20 parts by weight of compound no. 115 is dissolved in a mixture consisting of 80 parts by weight of xylene, 10 parts by weight of the adduct of 8 to 10 moles of ethylene oxide and 1 mole of oleic acid-N-monoethanolamide, 5 parts by weight of the calcium salt of dodecylbenzene-sulfonic acid, and 5 parts by weight of the adduct of 40 moles of ethylene oxide and 1 mole of castor oil. By pouring the solution into water and uniformly distributing it therein, an aqueous dispersion is obtained.

III. 20 parts by weight of compound no. 113 is dissolved in a mixture consisting of 40 parts by weight of cyclohexanone, 30 parts by weight of isobutanol, 20 parts by weight of the adduct of 40 moles of ethylene oxide and 1 mole of castor oil. By pouring the solution into water and finely distributing it therein, an aqueous dispersion is obtained.

IV. 20 parts by weight of compound no. 115 is dissolved in a mixture consisting of 25 parts by weight of cyclohexanol, 65 parts by weight of a mineral oil fraction having a boiling point between 210° and 280° C., and 10 parts by weight of the adduct of 40 moles of ethylene oxide and 1 mole of castor oil. By pouring the solution into water and uniformly distributing it therein, an aqueous dispersion is obtained.

V. 80 parts by weight of compound no. 113 is well mixed with 3 parts by weight of the sodium salt of diisobutylnaphthalene-α-sulfonic acid, 10 parts by weight of the sodium salt of a lignin-sulfonic acid obtained from a sulfite waste liquor, and 7 parts by weight of powdered silica gel, and triturated in a hammer mill. By uniformly distributing the mixture in water, a spray liquor is obtained.

VI. 3 parts by weight of compound no. 115 is intimately mixed with 97 parts by weight of particulate kaolin. A dust is obtained containing 3% by weight of the active ingredient.

VII. 30 parts by weight of compound no. 113 is intimately mixed with a mixture consisting of 92 parts by weight of powdered silica gel and 8 parts by weight of paraffin oil which has been sprayed onto the surface of this silica gel. A formulation of the active ingredient is obtained having good adherence.

VIII. 40 parts by weight of compound no. 115 is intimately mixed with 10 parts of the sodium salt of a phenolsulfonic acid-urea-formaldehyde condensate, 2 parts of silica gel and 48 parts of water to give a stable aqueous dispersion. Dilution in water gives an aqueous dispersion.

IX. 20 parts by weight of compound no. 113 is intimately mixed with 2 parts by weight of the calcium salt of dodecylbenzenesulfonic acid, 8 parts by weight of a fatty alcohol polyglycol ether, 2 parts by weight of the sodium salt of a phenolsulfonic acid-urea-formaldehyde condensate and 68 parts by weight of a paraffinic mineral oil. A stable oily dispersion is obtained.

In these application forms, the agents according to the invention may also be present together with other active ingredients, for example herbicides, insecticides, growth regulators, and fungicides, and may furthermore be mixed and applied together with fertilizers. Admixture with other fungicides frequently results in an increase in the fungicidal spectrum.

USE EXAMPLE Action on Plasmopara viticola

Leaves of potted vines of the Muller-Thurgau variety were sprayed with aqueous suspensions containing (dry basis) 80% of active ingredient and 20% of emulsifier. To assess the duration of action, the plants were set up, after the sprayed-on layer had dried, for 8 days in the greenhouse. Then the leaves were infected with a zoospore suspension of Plasmopara viticola. The plants were first placed for 48 hours in a water vapor-saturated chamber at 24° C. and then in a greenhouse for 5 days at from 20° to 30° C. To accelerate and intensify the sporangiophore discharge, the plants were then again placed in the moist chamber for 16 hours. The extent of fungus attack was then assessed on the undersides of the leaves.

The results show that active ingredients 113 and 115, applied as 0.05 wt % spray liquors, had a better fungicidal action (95%) than prior art comparative agent A (60%).
